Specification of Letters Ir'atent. Patnted July 13 1920 Original application filed .Tune 173, 1918, Serial No. 239,711; Divided and this application'led February Bc it lrnown that l, NiL'Linir Francis Di: BRANDT, a subject of the Republic of France,

and resident -of Melbourne, in the State of Victoria, Commonwealth of Australia, secretary, have invented certain new and usefui Improvements in and Relating to Harvesting-Machines, of which the following is a specification.

This invention relates to improvements in harvesting machines and has been devised in `orderto increase the utility thereof.

An essential feature of the invention consists in the means employed forcompensating for any inequality of the surface of theV ground over which the machine is traveling. In order that the invention may be more readily'understood it will now be described with reference to the accompanying drawings in which the invention is illustrated and adapted to header harvesting mechanism mounted on a frame `having draft appliances arranged on either side thereof be.- tween the front steering wheels and the rear wheels.

This application is a division of my copending application Ser. No. 239,711, filed J une 13, 1918, for harvesting machines. In the drawings Y k Figure 1 is a view in vertical central section, and

Fig. 2 is a view in plan of the improve-l portedby` suitable stays and having a swivel or fined division. i

Thedivision of the main frame bars 2 1s illustrated inthe drawings at '104 which at the division are held together by a strengthening plate. 105 arranged within the channel and bolted to the bars or beams 2 on either.y side of the division.

The front portions 3 of themai-n beams 2 are bentoutwardly and forwardly to allow clearance for the gear casing 127'of the yreaper frame 88 and support the stub axles of the front steering wheels T19 which are steered'by any suitable means.

lowered in any suitable way as for instance by a threaded nut loosely connected to the frame 38 and a threaded bolt 72, engaging the nut,'said bolt 72 being held in a support 73 on either side and at the ends 3 of the /main beams 2, the threaded bolts being operated in any convenient manner and preferably as illustrated in United States serial application No. 239,711 filed June 13th, 1918 of which this isa division.

The reaper frame carries reaper mechamsm of any suitable design but when tted to a header harvester, the preferred arrangement consists of the comb 42, reciprocating knife 43, belt conveyers 4:6, delivering the heads to a central rearwardly projecting conveyerd driven from the fulcrum spindle 35 and delivering the material to an elevator 67 which in turn delivers the Vmaterial to a grain boX 68 or to winnowing-and threshing mechanism as desired. l

VBeaters la` partially incased in a drum 16 operate` over the comb l2 inthe manner illustrated and throw the material on to the oonveyers 46. y i

To the side of the main beams 2 andbetween the front wheels 19 and the rear 1 wheels `9, provision is made for .the mounting `of draft appliances tothe front draft beam 18 and the rear draft beam 15, the 4latter being tted to the swiveledframe 106b carrying the rear wheels 9, the mounting of this frame allowing of surface inequalities of the ground-to be taken up.

To accomplish this function, the main frame is fitted with cross-beams 106 which connect by means of pivot pins or bolts 106, with the frame 106b vwhich carries the rear aXle 6- and wheels 9.

Pivots 106Il arranged in this way would allow of they taking up of any inequality of the surface of the ground overiwhich the machine is traveling and it will be readily understood that these pivots could, if desired, be mounted above the level of the main frame. i

In the, construction illustrated, the driving mechanism consists preferably of a variable speed gear 6il of suitable design fitted to the rear axle 6 and controlled by a clutch operated from the drivers seat.

From the variable speed gear, chains 114:
